This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Spectral-Analysis-of-Surface-Waves (SASW) method is an accepted means of measuring shear wave velocity (VS). In some settings, SASW measurements have produced results that were inconsistent with results from other methods of measurement. The effectiveness of the SASW methodology at complex geotechnical sites was investigated to identify site conditions where the SASW approach may produce erroneous results. Analytical simulations of surface wave measurements were performed. A traditional SASW methodology (global analysis), and a more rigorous approach (array analysis) were used to generate experimental dispersion curves. The effectiveness of these approaches was evaluated by comparing the experimental results to the true dispersion curve. The global analysis yielded dispersion curves that tend to underestimate surface wave velocities at long wavelengths. The array approach worked well for both simple, gradually increasing VS profiles as well as for some complex profiles with large VS contrasts. In some cases both the global and array analysis produce an experimental dispersion curve that is not consistent with the theoretical dispersion curve, especially for soft-over-stiff profiles, a common profile encountered in the field. These results have implications for earthquake site response analysis.
Book Synopsis SASW Measurements at Geotechnical Sites Overlaid by Water by : JM. Roesset
Download or read book SASW Measurements at Geotechnical Sites Overlaid by Water written by JM. Roesset and published by . This book was released on 1994 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Spectral-Analysis-of-Surface-Waves (SASW) technique is a nonintrusive, nondestructive technique that employs surface waves of the Rayleigh type to determine the layer thicknesses and stiffnesses of subsurface profiles. The SASW technique has been developed and successfully used on land. This paper extends the method to sites overlaid by water. A theoretical model has been developed to study the "surface" waves that propagate along a soil-water interface using a half-space overlaid by water as an approximation. The waves at the soil-water interface are termed "Scholte" waves. Results from the theoretical model show that in "deep" water, defined as a water depth exceeding the wave length of the Scholte wave, the effect of water is to reduce the surface wave velocity slightly from the velocity for a similar surface (Rayleigh) wave with air over the surface. Results of experimental studies are also described and shown to compare well with theoretical predictions.

Book Synopsis Inversion Method for Spectral Analysis of Surface Waves (SASW) by : Maria Catalina Orozco
Download or read book Inversion Method for Spectral Analysis of Surface Waves (SASW) written by Maria Catalina Orozco and published by . This book was released on 2003 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on estimating the shear wave velocity (Vs) profile based on the dispersion curve obtained from SASW field test data (i.e., inversion of SASW data). It is common for the person performing the inversion to assume the prior information required to constrain the problem based on his/her own judgment. Additionally, the Vs profile is usually shown as unique without giving a range of possible solutions. For these reasons, this work focuses on: (i) studying the non-uniqueness of the solution to the inverse problem; (ii) implementing an inversion procedure that presents the estimated model parameters in a way that reflects their uncertainties; and (iii) evaluating tools that help choose the appropriate prior information. One global and one local search procedures were chosen to accomplish these purposes: a pure Monte Carlo method and the maximum likelihood method, respectively. The pure Monte Carlo method was chosen to study the non-uniqueness by looking at the range of acceptable solutions (i.e., Vs profiles) obtained with as few constraints as possible. The maximum likelihood method was chosen because it is a statistical approach, which enables us to estimate the uncertainties of the resulting model parameters and to apply tools such as the Bayesian criterion to help select the prior information objectively. The above inversion methods were implemented for synthetic data, which was produced with the same forward algorithm used during inversion. This implies that all uncertainties were caused by the nature of the SASW inversion problem (i.e., there were no uncertainties added by experimental errors in data collection, analysis of the data to create the dispersion curve, layered model to represent a real 3-D soil stratification, or wave propagation theory). At the end of the research, the maximum likelihood method of inversion and the tools for the selection of prior information were successfully used with real experimental data obtained in Memphis, Tennessee.

Book Synopsis Automation of Spectral Analysis of Surface Waves Method by : S. Nazarian
Download or read book Automation of Spectral Analysis of Surface Waves Method written by S. Nazarian and published by . This book was released on 1994 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: With minimal simplifying assumptions and approximations, an automated version of the spectral analysis of surface waves (SASW) method has been developed to determine in situ shear wave velocity profiles of soil deposits. Testing time for each site, including collection of data, construction and inversion of dispersion curve, should not be more than thirty minutes. To accelerate field testing, a multi-sensor geophone array and a PC-based data-acquisition, signal-analysis package have been developed. The two greatest challenges have been the development of a fully-automated procedure to construct the dispersion curve from field data and a fast yet, theoretically-sound, inversion process to determine the shear wave velocity profile from a given dispersion curve. In this paper, the major theoretical and practical aspects of these two steps are described and discussed with examples.
